App Tab Cleaner does not collect, transmit, sell or share any data. There are no analytics, no telemetry and no network requests.


| Permission | Why | Where the data goes |
|---|---|---|
| tabs | Read tab URLs to check them against your rules, and close matching tabs. | Nowhere. URLs are compared in memory and never stored or sent anywhere. |
| storage | Save your rules and the pause setting. Pending countdowns are kept in session storage so they survive the background worker restarting. | Your browser's extension storage. If you use browser sync, your browser syncs the rules between your own devices; the extension itself never sends them anywhere. |
| alarms | Close tabs reliably when a timeout is longer than about 25 seconds. | Nowhere. |
| notifications (optional) | Only requested if you turn on "Notify before closing". Shows a local system notification naming the rule and timeout. | Your operating system's notification centre. |

The extension has no host permissions and never reads page content.
